First, the user that created the group needs to invite you to the group by following this process:
-click on the name of the group.
-click on Members.
-type in your email address or username and then click Invite.
Once a user invites you via your email address, you will get an email notification in your email inbox. You can accept the invitation via the email by clicking on Join Group.
You can also accept an invitation by going to your Account page on Ji Tap, once you’re logged in, and clicking on accept invitation on your Account page. You can access your Account page by clicking on the scroll down menu that appears when you click on your name on the top left hand corner on the site, once you’re logged in. This process works for both those that were invited by their username or email address.
